The MOUSE_EVENT_RECORD structure is used in a console INPUT_RECORD structure to report mouse input events .
dwMousePosition
Specifies the location of the mouse pointer in terms of screen buffer character cell coordinates.
dwButtonState
Indicates the status of the mouse buttons. The least significant bit corresponds to the leftmost mouse button. The next least significant bit corresponds to the rightmost mouse button. The next bit indicates the next-to-leftmost mouse button. The bits then correspond left-to-right to the mouse buttons. A bit is 1 if the button was pressed.
dwControlKeyState
Indicates the state of the control keys. Key state flags are:
| Value | Meaning |
| RIGHT_ALT_PRESSED | The Alt key is pressed. |
| LEFT_ALT_PRESSED | The Alt key is pressed. |
| RIGHT_CTRL_PRESSED | The Ctrl key is pressed. |
| LEFT_CTRL_PRESSED | The Ctrl key is pressed. |
| SHIFT_PRESSED | The Shift key is pressed. |
| NUMLOCK_ON | The NumLock light is on. |
| SCROLLLOCK_ON | The ScrollLock light is on. |
| CAPSLOCK_ON | The CapsLock light is on. |
| ENHANCED_KEY | The key is enhanced. |
dwEventFlags
Indicates the type of mouse event. If 0, the event indicates that a mouse button was pressed or released. Otherwise, the value is one of the following:
| Value | Meaning |
| MOUSE_MOVED | The event represents a change in mouse position. |
| DOUBLE_CLICK | The event represents the second click (button press) of a double mouse click. The first click is returned as a regular button press event. |
Mouse events are placed in the input buffer when the console is in mouse mode (ENABLE_MOUSE_INPUT).
Mouse events are generated whenever the user moves the mouse, or presses or releases one of the mouse buttons. Mouse events are placed in a console's input buffer only when the console group has the keyboard focus and the mouse pointer is within the borders of the console's window.
